The MidOpt Bi940 Near-Infrared (IR) Interference Bandpass Filter is commonly used with IR LED or laser diode illuminators
The GOYO GMTHR412514MCN is part of the GMTHR series
1550nm light is also generally considered to be “eye safe” (and safe for CMOS camera sensors)
The MidOpt NF550 Magenta Dichroic Shortpass Filter (Green Block) blocks green wavelengths while allowing shorter wavelengths
Narrow Near-Infrared (IR) Bandpass Filter, 928-955nm - MidOpt BN940 Bandpass The MidOpt Bi940 Near-Infrared (IR)The MidOpt BN940 Narrow Near Infrared (IR) Bandpass Filter is commonly used in remote control devices and in security surveillance lighting. 940nm illumination is often considered covert, as little, if any, faint red glow is produced from these LEDs, even in complete darkness. CCD and CMOS cameras have greatly reduced sensitivity at these wavelengths, and strong ambient light can often make imaging in this range very difficult. MidOpt Bandpass Filters
